Built in 1950, Higgins Hall was named in honor of Lothrop D. Higgins, a science professor who became the school's second principal while the university was known as Danbury State Normal School. In 1962, an addition called Higgins Annex was added to the Hall, nearly doubling the size of the building to more than 85,000 square feet.

Today Higgins Hall/Higgins Annex houses the mathematics department, the Academic Advisement Center, nursing laboratories, the ConnCAPP/ Upward Bound Program and the Educational Achievement and Access Program (EAP). Since the opening of the Science Building, Higgins has been in a state of transition, awaiting its renovation to meet future campus needs.
